Correlations ranged from 0.45–0.82 (all p-values<0.001) between the two assessments, and ICCs were 0.46–0.87 (all p-values<0.02). Additionally, none of the Eyestat parameters were significantly associated with biological sex, sleep status, or prior concussion history (all p-values>0.05).\u0000 \u0000 \u0000 \u0000 This study suggests substantial test–retest reliability of the EyeStatTM device across 10 parameters in a cohort of healthy high school athletes. The findings support the potential utility of the EyeStatTM device as a reliable baseline measure for assessing the blink reflex among young athletes.\u0000","PeriodicalId":8176,"journal":{"name":"Archives of Clinical Neuropsychology","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141672909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
